A four position hoist control determines the operation of the dump body. The hoist control is located to the left of the operators seat. The hoist control contains spring returns. The lever will move from the RAISE position to the HOLD position when the operator releases the lever. And, the lever will move from the LOWER position to the FLOAT position when the operator releases the lever. The four positions of the hoist control are: RAISE, HOLD, FLOAT and LOWER.The hoist control is connected to the hoist control position sensor which is a Pulse Width Modulated (PWM) sensor. The PWM sensor sends duty cycle input signals to the Chassis Electronic Control Module (Chassis ECM). Depending on the position of the sensor and the corresponding duty cycle, one of the two solenoids located on the hoist control valve is energized. The sensor provides a duty cycle signal that changes for all positions of the hoist lever. The duty cycle signal allows the operator to modulate the speed of the hoist cylinders.
